由于球墨鑄鐵的球狀石墨微觀結構，在減弱振動能力方面，球墨鑄鐵優于鑄鋼，因此更加有利于降低應力。選擇球墨鑄鐵的一個重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎，鑄造效率更高，也較少了球墨鑄鐵的機加工成本。球墨鑄鐵的強度和鑄鋼的強度是可比的。球墨鑄鐵具有更高的屈服強度，其屈服強度*低為40k，而鑄鋼的屈服強度只有36k。在大部分市政應用領域，如：水、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和*氧化性都超過鑄鋼。
Due to the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is better than cast steel in reducing vibration, so it is more conducive to reducing stress. An important reason for choosing nodular cast iron is that the cost of nodular cast iron is lower than that of cast steel. The low cost of nodular cast iron makes this material more popular, higher casting efficiency and less machining cost of nodular cast iron. The strength of nodular cast iron is comparable to that of cast steel. Nodular cast iron has higher yield strength, and its yield strength * is as low as 40K, while the yield strength of cast steel is only 36K. In most municipal applications, such as water, salt water, steam, etc., the corrosion resistance and oxidation resistance of nodular cast iron are higher than that of cast steel.
他的抗震和抗腐蝕性強。噴水腐蝕試驗，九十天的腐蝕量僅為灰鑄鐵井蓋的1/40，是灰球墨井蓋的1/10。使用壽命是復合井蓋和水泥井蓋的2倍，河南球墨鑄鐵井蓋是普通灰鐵井蓋的5倍。球墨鑄鐵井蓋只有我們對球墨井蓋進行合理的使用與耐心的維護，它的使用壽命才會延長的奧。
He is strong in earthquake resistance and corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only 1 / 40 of that of gray cast iron well cover and 1 / 10 of that of gray nodular graphite well cover. The service life of well cover made of Henan gray iron and cast iron is 5 times that of ordinary well cover. The service life of nodular cast iron manhole cover will be prolonged only if we use it reasonably and maintain it patiently.
（6）稀土鎂球墨鑄鐵。在高強度低合金球墨鑄鐵方面，除了對銅、鉬研究較多外，還對鎳、鈮等進行了研究。在利用**釩鈦生鐵制作釩鈦合金球墨鑄鐵方面，中國國內一些單位進行了大量、系統的工作。中錳球墨鑄鐵雖然在性能上不夠穩定，在系統研究與生產應用，取得了顯著的經濟效益。球墨井蓋主要應用領域：市政道路，高速公路，通信，電力，自來水，小區，學校等各種園區。
(6) Rare earth magnesium nodular cast iron. In terms of high strength and low alloy nodular cast iron, in addition to copper and molybdenum, nickel and niobium were also studied. Some units in China have done a lot of systematic work in the production of vanadium titanium alloy nodular cast iron from * * vanadium titanium pig iron. Although the properties of medium manganese nodular cast iron are not stable enough, remarkable economic benefits have been obtained in systematic research and production application. Main application fields of nodular well covers: municipal roads, highways, communications, electric power, tap water, residential areas, schools and other parks.
球墨井蓋能裝飾城市道路。馬路上的球墨井蓋很多，鑄鐵井蓋上面的花紋、字樣都不一樣，井蓋的用途也不一樣，下面為大家介紹一下這些井蓋井底下面的世界1、排水工程井蓋：于雨水、污水管線。2、給水工程井蓋：應用于自來水、消防工程等。3、供熱工程井蓋：應用于熱力臂線。4、供電工程井蓋：應用于電力供應纜線、電信工程、電話、通信電纜管線。5、園林工程井蓋：應用于配套綜合管線。6、燃氣工程井蓋：應用于煤氣工程、**氣管線等。7、路燈工程井蓋：應用于供電、照明、電纜管線。
Nodular well covers can decorate urban roads. There are many nodular well covers on the road. The patterns and words on the cast-iron well covers are different, and the purpose of the well covers is also different. Here is a brief introduction to the world under the bottom of these well covers. 1. Well covers of drainage engineering: for rainwater and sewage pipelines. 2. Well cover of water supply engineering: used in tap water, fire engineering, etc. 3. Well cover of heating engineering: applied to thermal arm line. 4. Well cover of power supply engineering: it is applied to power supply cable, telecommunication engineering, telephone and communication cable pipeline. 5. Garden engineering well cover: used for supporting comprehensive pipelines. 6. Gas engineering well cover: used in gas engineering, * * gas pipeline, etc. 7. Street lamp engineering well cover: used for power supply, lighting and cable pipelines.
